I'm trying to give elevation to corners of cardview

Question

I'm trying to provide elevation to the corners of cardview. my requirement is elevation should n't effect at the middle of cardview. it should effect only corners like image shown below.

As shown in image, at the middle of the cardview elevation should be zero at corners there should be some elevation (for example: elevation:4dp)

Here is the code i tried so far

 <android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
                                            xmlns:card_view="http://schemas.android.com/apk/res-auto"
                                            android:layout_width="match_parent"
                                            android:layout_height="wrap_content"
                                            android:layout_marginLeft="10dp"
                                            android:layout_marginRight="10dp"
                                            android:layout_marginTop="10dp"
                                            android:background="@null"
                                            android:gravity="center"
                                            card_view:cardBackgroundColor="@android:color/white"
                                            card_view:cardCornerRadius="4dp"
                                            card_view:cardElevation="3dp">

Try setting card_view:cardUseCompatPadding="true"

So your xml should look like:

<android.support.v7.widget.CardView
            xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:card_view="http://schemas.android.com/apk/res-auto"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginLeft="10dp"
            android:layout_marginRight="10dp"
            android:layout_marginTop="10dp"
            android:background="@null"
            android:gravity="center"
            card_view:cardBackgroundColor="@android:color/white"
            card_view:cardUseCompatPadding="true"
            card_view:cardCornerRadius="4dp"
            card_view:cardElevation="3dp"/>
